Since the Linux console has no connection to the X server, in that
terminal you can speed up Vim startup considerably by using the -X
command-line switch.
Even in Console mode, Vim compiled with +x11 will try to connect to the
X server at startup because it still uses X for the +clipboard and/or
+clientserver features, to save and restore the console window title,
its contents (+xterm_save), and to "save itself" at X-windows closedown
(+xsmp or +xsmp_interact).
Best regards,
Tony.

English is the only major language in which "I" is capitalized; in many
other languages "You" is capitalized and the "i" is lower case.
